Hi Carol, Here's what I like:

What I do when I have left over baked chicken (Or leftovers from the
Colonel), is to break the chicken up into small bite size pieces making
sure that I'm not using any gristle, fat, skin, and place about a cup,
or more of this into a small saucepan, with lid.

Add about a rounded tsp Paprika, rounded tsp Chili powder, a dash of
garlic powder, a small dash of Cumin, a dash of Black Pepper, and I'll
add to the pan about 4 tablespoons of water, mix, and simmer on low heat
mixing for a few minutes.
Sample, and if you think it use a tad more salt, add to taste, but be
careful.

The idea is to give the Chicken a little bit of Character. but not to
overdo it, that the chicken flavor is totally lost. Cumin, and Garlic
are powerful seasonings, so be careful with these.

Then, I'll take fresh Corn Tortillas, fry them in oil in a small fry pan
for about 20-30 seconds each till they crisp up a bit, and drain on
paper towels.
I'll use two Tortillas per Taco, and in between the Tortillas, I'll
place a slice of Kraft American Cheese. Spoon a couple tablespoons of
the chicken mixture onto the Tortillas, and then add condiments like
Cilantro/Onion/Lettuce/Avocado/Tomato/Hot Sauce.

I guarantee you'll like these! Very tasty! Mark
